Death Star 23

Death Star 2-23

Here's how to get 3 stars on Death Star 23 in Angry Birds Star Wars:

Bird 1: Fire your blue splitting pig at the bottom portion of the stacked blocks. Specifically, at the ice block in between the word blocks. Split it before it makes contact and it should topple most of the structure.

Bird 2: Aim your Yellow Han Solo Bird directly at the remaining pig in the alcove, and fire your blaster at it. There should be enough damage to take him out.
